IMPROVEMENT IN PAPER-TRIMIVIING MACHINES.

Specification forming part of Letters Patent No. 119,066, dated August 15, 1871.

To all whom it may concern:

Be it known that we, ORLANDO L. STARKEY and ELISHA W. BOSTON, of Fort Wayne, in the county ofAllen and State of Indiana, have invented certainnew and useful Improvements in Wall- Paper Butting-lvlachines; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a front elevation, partly in section. Fig. 2 is a top view, and Fig. 3 a vertical transverse section of our improved wall-paper buttingmachine. Fig. 4 is a detached view of one end of cylinder B.

Similar letters of reference indicate corresponding parts.

The nature of our invention consists in the arrangement and construction of an apparatus to be used for butting both edges of wall-paper at the same time, by the simultaneous action of two sets of rota-ting cutters, whose edges pass each other in such a manner as to cut like shears, said cutters being arranged on rotating cylinders,v between which the paper to be operated is fed. One set of cutters is stationary, while the other is made adjustable, so as to meet the requirements of different widths of paper. Our invention re-` lates particularly to the arrangement and adjustment of the cutters, both in relation to the desired width of paper, and also t0 the device by which the cutting-edges of the adjustable cutters are held in continual contact, as will be more fully described.

To enable others skilled in the arts to make and use our invention, we will nowproceed to describe its construction and operation.

A represents a cylinder, which is secured in suitable bearings on a convenient frame. This cylinder is composed of two sections, a and b. Section a is fixed permanently to the axle, and revolves with it. This section is provided with a cutting flange or disk, c, which is secured to said cylinder near its outer end, as seen in Fig. l. Section b of cylinder A is iitted on the axle so as to be adjustable longitudinally to any desired width while it revolves with the axle. The adjustable section of cylinder A is also provided with a cutter, d, in every respect similar to cutter c. The surface of this cylinder is covered with iiock, so as to present a slightly-yielding surface, which enables the cylinder to take a firm hold on the paper without in the least injuring it. The outer end of section b is provided with a metallic iiange, c, as seen in Fig. l. B represents a cylinder, which is placed directly over cylinder A, where it is secured in suitable bearings ff. These bearings are adjustable vertically, and are held in position by means of spiral springs, as seen in Fig. 1, so as to allow said cylinder B to accommodate itself to any thickness of paper or any irregularities therein. The geueral arrangement of the cylinder B is, so far as the sections thereof and the cutters thereon are concerned, exactly identical with the lower cylinder A. It being' divided in sections c and b', it is also provided with cutting-disks c and d. These disks are made somewhat concave, and are so placed as to bring their concave sides facing each other, thus presenting a shear-like surface to the paper. The outer end of section b is provided with an adjustable metallic thimble or sleeve, which fits over the outer end of the section, as seen in the drawing, around this thimble there is a groove, g, into which flange e ts slingly, for the purpose of holding the sections in their relative positions at any 'point of adjustment. A spiral spring, l', is inserted in or applied to a suitable seat in the end of section b of cylinder B, as seen in Fig. 4, and serves to force said cylinder longitudinally so as to press the edges ofthe cutting-disks together. i represents a nut, through which a screw, j, passes. The said nut is, on its lower side, provided with a lip, lb, which extends downward and enters the groove g. When the screw j is rotated the nut is traversed over said screw, and carries with it the section b of cylinder B. The movement of said section also carries section b of cylinder A in the same direction, the two sections always maintaining the same relative position. Thus the cutters on the .sections b b of the cylinders may be, at will, soY adjusted in relation to their distance from the cutters c c on the not-adjustable parts of the cylinders as to be adapted to cut any desired width of paper. At the outer end of the cylinder A a spiral spring, k, is or may be inserted in a suitable seat formed in the end of the cylinder over the axle, which presses against the side of the frame for the purpose of meeting and resisting the pressure of the spring in the opposite end of section b of cylinder B. These two springs act in combination for the purpose oi" constantly engaging the cutting-edges of the disks while operating, as before described. D represents a reel, which receives the paper which has passed through the machine7 and is operated by means of a set oi' suitable pulleys and belt. E represents a receiving-roller7 which assists in delivering the paper from the cutters to rcel l). F represents a guide xed to or made adjustable on a table, Ll, so that it greatly facilitates feeding the paper to the cutters and keepin g it in line with them. G represents the guide, which is adjusted laterallyY by inea-ns of a screw, a, which passes through a suitable nut secured to the under side ol' the guide7 which is held in position by it. This guide G has on its inner side a sin-ing, o, against which the end of the roll of paper to be operated upon is pressed by the hand of the ol'rerator. When the guide is placed in the proper position the roll of paper through which the rod m is passed is placed in position and is forcedv by the hand against the spring, and the end of the paper is inserted between the rollers or cylinders, the cutters of which are adjusted to the desired width7 and the apparatus is put in operation. If the paper is found to deviate from the desired line7 it is pressed with more force against the spring, or it is relieved so as to shift it to the desired line of travel without stopping,l the machine.

Having-thus described our invention, we claim as new and desire to secure by Letters Patent- The cylinders A and B, provided with cutters c c and d d', iiange e, and groove g, spiral springs l and 7c, nut and screvsT adjustment z' and j, all combined and operating,` in the manner and for the purposes substantially as described.
